Systems and methods to provide privacy protection and brightness enhancement in an interactive environment

Abstract

Described herein are systems and methods to provide privacy protection and brightness enhancement in an interactive environment. A system may include one or more of a headset, one or more light sources, one or more optical elements, one or more physical processor, and/or other components. A light source may be configured to generate linearly polarized light rays polarized on a first polarization plane along an axis of propagation. A reflective polarizer of an optical element may be configured to transmit light rays polarized on a second polarization plane transverse to the first polarization plane. Light rays polarized along the first polarization plane may be reflected off the reflective polarizer. An absorptive polarizer of an optical element may transmit light rays polarized on the second polarization plane so that light rays polarized along the second polarization plane may be transmitted through both the absorptive polarizer and the reflective polarizer.

Description

FIELD OF THE INVENTION[0001]The system and methods described herein relate to provide privacy protection and brightness enhancement in an interactive environment, such as an augmented reality environment and / or a virtual reality environment.BACKGROUND OF THE INVENTION[0002]There are many types of vision systems that provide virtual or augmented reality (AR) displays. In particular, wearable technology such as head mounted displays (HMD) are becoming more popular.SUMMARY[0003]One or more implementations of a system described herein facilitate providing views of virtual content (e.g., virtual objects in the form of three-dimensional digital imagery) in an interactive environment, such as one or both of a virtual reality environment and / or an augmented reality environment. An augmented reality environment may include views of images of virtual content superimposed over views of a real-world environment. A virtual reality environment may include views of images of virtual content within...

Benefits of technology

[0008]A reflective polarizer may be configured to transmit light rays polarized on a polarization plane that may be transverse to the polarization plane of a given light source. The light rays polarized along the polarization plane of a light source may be reflected off the reflective polarizer and directed toward one or more eyes of the user when the headset is installed on the head of the user. The reflective polarizer may enhance the reflection of images off the optical element so that the images may be brighter (e.g., fewer light rays may be leaked to the ambient environment) and / or may reduce or eliminate the observability of reversed images by an outside viewer.

[0009]An absorptive polarizer may be arranged downstream from a reflective polarizer with respect to the propagation of light rays generated by a given light source. The absorptive polarizer may be configured to transmit light rays polarized on the polarization plane that may be transverse to the polarization plane of the given light source. When the headset is installed on the head of the user, light rays from an ambient environment surrounding the user that are polarized along the transverse polarization plane and propagating toward the optical element may be transmitted through both the absorptive polarizer and the reflective polarizer to the one or more eyes of the user. The absorptive polarizer may reduce or eliminate reflection(s) an observer may see when looking at the headset.
